验证码死都不显示 只好来求助大家了

我刚进这个公司，前一个写程序的走了，没有留下开发文档，自己熟悉了几天代码，我从服务器上面把程序把数据库复制到了本地，配置环境 都配置好了 开始的时候验证码能显示，后台登录的验证码一直不能显示，蛋疼了一个星期了，各位帮我参谋参谋。。网上说的办法我都试过了，开启了父路径，开启ADODB.Stream了组件，浏览器没问题，我估计是验证码文件的问题，因为我一直找不到random验证码文件。<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<Jetway.Web.Areas.Admin.Models.AdminSignIn>" %>

解决方案 »

  1.   

    看看你的代码是否有问题或者你的文件路径<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/ValitionNo.aspx" />
    ValitionNo.aspx是生成验证码文件
      

  2.   

    点击图片右键属性，查看url地址是什么
      

  3.   

    http://127.0.0.1/captcha-image/render/0.0005715132218908625  属性是这个
      

  4.   

    那你就在浏览器地址栏里面输入http://127.0.0.1/captcha-image/render/0.0005715132218908625看显示或者提示什么？
      

  5.   

    郁闷 上传不了图片 打开http://127.0.0.1/captcha-image/render/0.0005715132218908625 显示：
    无法找到该页
    您正在搜索的页面可能已经删除、更名或暂时不可用。 
    --------------------------------------------------------------------------------请尝试以下操作：•确保浏览器的地址栏中显示的网站地址的拼写和格式正确无误。
    •如果通过单击链接而到达了该网页，请与网站管理员联系，通知他们该链接的格式不正确。 
    •单击后退按钮尝试另一个链接。
    HTTP 错误 404 - 文件或目录未找到。
    Internet 信息服务 (IIS)--------------------------------------------------------------------------------技术信息（为技术支持人员提供）•转到 Microsoft 产品支持服务并搜索包括“HTTP”和“404”的标题。
    •打开“IIS 帮助”（可在 IIS 管理器 (inetmgr) 中访问），然后搜索标题为“网站设置”、“常规管理任务”和“关于自定义错误消息”的主题。    而服务器上面的 访问能看到验证码
      

  6.   

    一般应该是这样写吧
    http://127.0.0.1/captcha-image/render
    带随机数应该
    http://127.0.0.1/captcha-image/render/?0.0005715132218908625
      

  7.   

    程序是从服务器上面拷贝下来的。。数据库什么都是好的 我纳闷公司电脑2003的系统和win7的系统都不能显示，我家里的笔记本winxp也不能显示  就服务器上面能显示
      

  8.   

    打开net_lover说的
    http://127.0.0.1/captcha-image/render/?0.0005715132218908625 显示Server Error in '/' Application.

    0.0005715132218908625 这个数值是生成的验证码iis里面配置通配符映射 请教下 怎么配置
      

  11.   

    通配符设置方法
    http://www.google.com.hk/search?q=iis%20%E9%80%9A%E9%85%8D%E7%AC%A6%E6%98%A0%E5%B0%84&oe=utf-8&rls=org.mozilla:zh-CN:official&client=firefox-a&um=1&hl=zh-CN&biw=1366&bih=585&ie=UTF-8&sa=N&tab=iw&ei=imT5Tvb9GI2WiQfohLm8AQ
      

  12.   

    另外，错误提示说你的 Session采取的是StateServer方式的，你需要启动 ASP.NET State 服务，并配置连接，开放端口等
      

  13.   

    置通配符映射  C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll  直接就打不开网页了 晕
      

  14.   

    http://127.0.0.1/captcha-image/render/ 能显示验证码了 后台不能显示 郁闷
